As far as I know, bitcoin is now considered as an asset and a payment method in some country. It's a very long way for bitcoin to be a currency.
Investors and early adopters like these (bitcoin) assets because they are untethered from the regular economy where fiat currencies, more traditional forms of exchange and value transfer reign the day. It is not without a sense of irony that part of Bitcoins rapid ascent this year is owed to the fact that traditional economy players are now paying close attention to this asset class. While some of this attention remains negative, profoundly confused or ambivalent, such as China and South Korea banning initial coin offerings ICOs along with ongoing attempts to regulate a fundamentally decentralized platform. Add to these negative views Jamie Dimons full-throated attack on Bitcoin including the threat of terminating any JP Morgan employee caught trading in the digital asset, and the unwelcome news levied against digital assets continues to mount. With each puff of hot air, however, as if in open revolt to traditional economic order, Bitcoin continues to defy the odds taking investors to stratospheric heights where the air begins to thin and bubbles traditionally deflate.
